Jung made significant contributions to knowledge of areas such as human
development and personality assessment. In terms of human development,
Jung emphasized that personality development occurs throughout the life
of the person. This was critical in that Freud’s theory, the dominant theory
at that time, emphasized the first five years of life in examining personality
development. The overall goal of the person in Jung’s approach to development
is the realization of the self, which is a long and difficult process. Unlike
Freud, Jung was particularly interested in development during the
adulthood years. He emphasized the changes that occur beginning at the
age of thirty-five or forty. He believed that this was often a time of crisis in the
life of the person. This notion of a midlife crisis (which Jung experienced
himself) has continued to be the source of significant theoretical and empirical
claims.
Jung believed that the concept of a crisis during middle age was necessary
and beneficial. Often, a person has achieved a certain level of material success
and needs to find new meaning in life. This meaning can be realized by
shifting from the material and physical concerns of youth to a more spiritual
and philosophical view of life. The person seeks gradually to abandon the
emphasis on the conscious ego which is dominant in youth. A greater balance
between the unconscious and conscious is pursued. If this is successfully
achieved, the person can reach a state of positive psychological health
that Jung labels individuation. Perhaps the key to the midlife years in Jung’s
theory is that these are the years in which the person is attempting to discover
the true meaning of life. Finally, Jung stated that religion can play an
important role in life during the midlife and old-age years. During the
midlife years, a sense of spirituality rather than materialism is important in
personality development; looking at the possibility of life after death can be
positive for the older adult.
